The Henke Roux Ratchet Part 14/21 is a small replacement component used in veterinary instrument systems, specifically within Henke Roux and Swavet equipment. It forms part of the ratchet mechanism that allows controlled, step-by-step operation in dosing or applicator tools. This part is designed for compatibility with 14�21 mm range systems and is typically used to repair or maintain existing instruments rather than function as a standalone tool. It is compact, lightweight, and built for precision within the internal mechanism of the device.
